Title: Pulse frame for a time-multiplex system having a video channel and audio and data channels
Inventor: PIRSCH PETER DR ING
IPC: H04J3/16
Filed: 1984-10-30
Abstract: One of the known proposals for digital transmission of a video signal and a plurality of audio and data signals is for the video signal to be coded at approximately 70 Mbit/s, to be combined with audio and data signals to form a time-multiplex signal at 69.632 MHz and for two such time-multiplex signals to be in turn transmitted in time-multiplex with the bit-repetition frequency of the fourth stage of the pulse-code-modulated hierarchy. The present application specifies a suitable pulse frame for the multiplexer and demultiplexer which respectively form and resolve the 69.632 Mbit/s signal. Said pulse frame consists of 68 columns and 4 rows, which form 272 time sections, each having 16 bits, and has a repetition frequency of 16 kHz. 60 columns are reserved for the video signal, which is synchronous to the pulse frame. Data signals or pulse-code-modulated signals can be transmitted at multiples of 64 kbit/s in the other columns. <IMAGE>

Title: Process for producing a composite material from metal and short fibres
Inventor: KANTARDJIEW IWAN DR
IPC: B22D17/14
Filed: 1985-07-13
Abstract: Such a process employing impregnation exists, in which a ply of short fibres is provided, molten metal is provided on the short fibre ply and a molten metal is introduced under pressure into the ply of short fibres. It is then desirable that fibres from metal composite materials having improved properties can be produced by an easier, less complicated technology. This is achieved when the short fibres in the ply are provided in a random distribution and in a density of 1 g of short fibre per 1-40 cm<3> of volume in a mould, the molten metal is poured on top of the short fibre ply and a piston-like pressure is exerted upon the molten metal. Under the piston-like pressure, the melt further compacts the fibres of the ply and distributes them uniformly on the substrate; the melt then penetrates the distributed and compacted fibre mass.

Title: Electrical DC voltage converter system
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: H02M3/18
Filed: 1985-08-31
Abstract: Using further knowledge and progress on the electrical DC voltage converter system of the prior applications, the system (which is pulsed using a linear or rotating twelve-contact changeover switch) is enhanced in that the preference of the last application, specifically for twelve instead of only eight contacts on the changeover switch as in the past, is used in order to thus allow the utilisation (which has already occurred earlier but has not been usable until now) of the charging rails now to be usable as a capacitive charging energy store. In addition, the novel feature of the twelve-contact changeover switch allows a plurality of converters, for example the converters A, B, C shown, to be connected with their high voltages in series or in a mixed series-parallel manner via only two terminals in each case and hence further voltage rises and stepped high-voltage selection to be assisted.

Title: Secondary compressor for two and four-stroke internal combustion engines
Inventor: FOX GUIDO
IPC: F02B19/06
Filed: 1985-11-21
Abstract: The secondary compressor makes it possible to operate diesel engines, for example, without injection pump, thereby achieving improved swirling of the air-fuel mixture. This is achieved by a small piston with cylinder on the engine cylinder head, which is moved so that at the correct timing of the main piston it injects into the combustion chamber and triggers the spontaneous ignition. The volume of the comression cylinder is so designed that it can accommodate all the precompressed fuel-air mixture in it. The particular advantages of the device are: improved efficiency, reduced soot formation and the prevention of so-called knocking.

Title: Composite mat for roadway support
Inventor: SCHAEFER BERND
IPC: E21D11/15
Filed: 1986-01-28
Abstract: Composite mats are used in underground mining and tunnelling in order to connect the spaced-apart roadway support arches to one another in such a way as to secure the rock. At one end, the composite mats consisting of longitudinal and cross bars have a hook bent in the mat plane. At the other end, the composite mats have a coupling formed by a straight cross bar and a second coupling cross bar arranged at a distance from the straight cross bar. The coupling is simple to make and is especially easy to manipulate. The coupling cross bar has U-bends which are arranged at the spacing of the longitudinal bars, are dimensioned in accordance with the respective longitudinal bar and are arranged perpendicularly to the mat plane. The longitudinal bar ends are offset from the mat plane by double canting so that a mat network acting roughly continuously is obtained after the coupling is made. <IMAGE>
